Food for thought: Espanola company developing four-season greenhouse.

When Jeff Scharf first set up a prototype of his four-season greenhouse, he was mostly looking to test the performance of its envelope, and he planted a few seeds as an experiment. But he didn't anticipate just how well it would work.

"Within weeks we were cropping all our lettuce; our cucumbers were putting out 40 to 50 pounds per week, and we only have four plants," Scharf said. "It's been amazing."

In August, Scharf launched the design through Greenhouses Canada, an offshoot of the Helios Group of Companies, established by Scharf and his partner, Trevor Tario, four years ago. The greenhouse technology was developed in partnership with Cambrian Innovates, the research arm of Cambrian College, and Helios Whitefish River First Nation.

Espanola-based Helios, known for developing solar power technology, began working on the greenhouse idea four years ago after striking up a partnership with Whitefish River, located along the North Shore of Lake Huron.

"We always envisioned a community-based greenhouse operation as kind of our main focus, because the whole idea at the beginning was to help the Far North First Nation communities become self-sustaining with their food development," Scharf said. "That's basically what the model has been."

Conventional greenhouses constructed of glass can't be used year-round in areas with colder climates like Northern Ontario, limiting the growing season, Scharf noted. Remote First Nation communities are then forced to pay exorbitant amounts for produce that's flown in, and by the time it reaches the communities, it's lost most of its nutritional content.

Greenhouses Canada uses solar panel technology combined with existing technologies and growing methods, such as hydroponics and aquaponics. The solar panels are rated at an R value of 66, and are manufactured with easy installation in mind.

"We'll be able to manufacture the wall panels, get them shipped to site, and just basically assemble them like Legos once we're on site,"...
